It just occured to me -- there is a group of real pilots here who do
maintain coordinated with outside reference only. Those glider guys
who tape a piece of yarn to the middle of their windscreen never have
to look at the ball, do they?



They seem to spend so much of their time watching the ten other
gliders all turning in the same thermal and making sure they don't
bang into them that I doubt they'd want to be looking in the
cockpit!!!
